Description of key information
A valid OECD 216 study is available. no adverse effects could be determined for soil mircoorganisms. Effect concentrations (ECx) could not be calculated due to the lack of negative effects. The NOEC was determined to be < 62.5 mg/kg soil d.w. , however since no adverse effects could be determined, the test item is considered to have no long-term adverse effects on nitrate formation in soil at concentrations up to and including 1000 mg test item/kg soil dry weight.
Key value for chemical safety assessment
- Long-term EC10 or NOEC for soil microorganisms:
- 1 000 mg/kg soil dw
Additional information
The amounts of nitrate extractable from soils incubated for 28 days with different test item concentrations were significantly increased compared to the control at test item concentrations of 62.5 mg/kg soil dry weight and above. It is assumed that this effect was caused by the additional nitrate introduced into the soil via the test item.
Therefore, the NOEC was <65.5 mg/kg soil dry weight.
Effect concentrations (ECx) could not be calculated due to the lack of negative effects.Based on the above results, and the fact, that no adverse effects could be determined, the test item is considered to have no long-term adverse effects on nitrate formation in soil at concentrations up to and including 1000 mg test item/kg soil dry weight.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
